I have installed Xcode latest version(8.1) on my MAC (El Capitan 10.11.5) but when I tried to build MEX file in MATLAB 2015a I got the following error:

error using mex No supported compiler or SDK was found. For options, visit http://www.mathworks.com/support/compilers/R2015a/maci64.html.

If UAC (User Account Control) is turned on Windows 7, the MinGW support package might say success, but the compiler may not be there and mex won't find it. The reason for this is that xcopy silently fails due to UAC being turned on.

Resolution is to turn off UAC. Please follow the below link to turn off UAC:

Try to reinstall MingW compiler and see if it works.

Start up the Terminal application, which you can find in /Applications/Utilities . When you get to the command prompt, command

sudo xcode-select -switch /Applications/Xcode.app

and authenticate when it prompts you for your password.

After that xcode will be selected and you should be able to proceed.
